Just a brief note on something that has been bothering me for a while. In reading Prof. Campbell Harvey's Hypertextual Finance Glossary ( http://www.duke.edu/~charvey/Classes/wpg/glossary.htm ) I noticed that it contains the ISO 4217 Currency Codes, e.g. there is an entry for "USD" with the definition "The ISO 4217 currency code for the USA Dollar".   However, the ISO 4217 Currency Codes are sprinkled though the glossary, because all terms are arranged in alphabetical order (actually, lexicographical order since numbers and symbols have to be taken into account).

There is no guarantee that it is correct. Definition Authority: a Definition Reference that can be relied on. There is some kind of guarantee that it is correct. Definition Authoritative R
